INTRODUCTION TO
ECONOMICS: A SUMMARY
Economics is the study of how societies allocate scarce resources to satisfy unlimited wants
and needs. It is broadly divided into two main branches: Microeconomics and Macroeconomics.
Core Concepts
Microeconomics focuses on the decisions made by individual economic agents, such
as households, firms, and industries. It examines how these decisions affect the
allocation of resources and the prices of goods and services in specific markets. Key
topics include:
Supply and Demand: This fundamental law explains how the price of a good or
service is determined by the interaction between the quantity producers are
willing to supply and the quantity consumers are willing to demand. The
intersection of supply and demand curves determines the equilibrium price and
quantity in a market.
Elasticity: Measures the responsiveness of quantity demanded or supplied to
changes in factors like price, income, or the price of related goods. For example,
price elasticity of demand indicates how much the quantity demanded of a good
changes in response to a change in its price.
Market Structures: Refer to the characteristics of a market, such as the number of
buyers and sellers, the type of product, and barriers to entry. Examples include
perfect competition, monopoly, oligopoly, and monopolistic competition.
